Subject: [PATCH v3 0/7] Bluetooth Wacom merge into the USB driver

Hi guys,

so this patch series is intended to be applied on top of Dmitry's wacom branch.

This time, I had a closer look at the various moves, and checkpatch does not
complained on anything besides the "open brace { [which] should be on the
previous line".

In v3, the difference is that now, no functionality has been dropped thanks to
Przemo. The LEDs are working through the same API in BT and USB, and the OLEDs
has been unified. They use the same sysfs node, and the same scrambled API.
The only difference we have now is that BT expecta 1-bit images, while USB
4-bits images.

Przemo, I'll let you add your s-o-b line in 4/7.

Ping, I did not added your previous Acked-by (the patch set has been split since).
Feel free to comment on this part too :)

Cheers,
Benjamin

Subject: [PATCH v3 1/7] Input - wacom: prepare the driver to include BT devices

Now that wacom is a hid driver, there is no point in having a separate
driver for bluetooth devices.
This patch prepares the common paths of Bluetooth devices in the
common wacom driver.
It also adds the sysfs file "speed" used by Bluetooth devices.

Subject: [PATCH v3 3/7] Input - wacom: handle Intuos 4 BT in wacom.ko

A good point of this change is that now, the Intuos4 bluetooth can handle
the different tools (artpen, airbrush, mice), and we get a common interface
between USB and BT for accessing the LEDs/OLEDs.

Subject: [PATCH v3 5/7] Input - wacom: Remove passing id for wacom_set_report

From: Przemo Firszt <[email protected]>

Every call of wacom_set_report was passing "id" as a separate parameter
and buffer also passed the same information. We can use first u8 of the
buffer instead of "id"

Subject: [PATCH v3 4/7] Input - wacom: Check for bluetooth protocol while setting OLEDs

Bluetooth Intuos 4 use 1-bit definition while the USB ones use a 4-bits
definition. This changes the size of the raw image we receive, and thus
the kernel will only accept 1-bit images for Bluetooth and 4-bits for
USB.

I'd like to see Przemo's Tested-by tag here as well. Przemo, are you
done with your testing?

Thank you Przemo and Benjamin for your effort in making this
transition smooth and successful. We, at Wacom, are very grateful to
be part of this great community.

Look like you pressed "y" when git send-email asked for charset:

It kills git am:
